Apple’s Mighty Mouse Scroll Ball clogs too easily

“I purchased the Mighty Mouse, eventually, with skepticism, chiefly from reading an equal share of both positive and negative reviews. I remember taking a trek down to the Apple Store in Regent Street, London, with a couple of friends—who had iPod issues they were looking to sort– to buy this little rodent of a computer device. I got home that day, plugged it in, installed the drivers and I was away,” Aaron Wright writes for Apple Matters.

“My first reaction? Wow, excellent! I couldn’t understand why so many people were knocking this mouse, it was sort of a revolution as far as Apple products go, we finally had a two buttoned mouse,” Wright writes.

“However, that joy wasn’t going to last. I believe I purchased my Mighty Mouse around September 2005 and used it pretty much daily until about two weeks ago, when I finally decided enough was enough. I wasn’t fed up with any of the software functions of the mouse, nor was I disappointed with anything else the mouse had to offer, as such,” Wright writes. “I was actually fed up of using the little white piece of plastic because the scroll wheel [Scroll Ball] had completely clogged up. It had ceased to function and I was angry and frustrated that I could no longer take full benefit of the £40 I paid for it. I’m now planning to return it to the Apple store this weekend to see if I can get a replacement, but then I got to thinking, is there any point?”

“I look after my computer equipment quite well, especially considering the amount of money spent on it, I think it’s only right. But no amount of cleaning could prevent the [Scroll Ball] getting clogged up,” Wright writes. “Here’s something I now fear. Every new iMac sold since January, I believe, comes equipped with a Mighty Mouse as standard, no more singled-buttoned ‘Mouse.’ I’ve had my Mighty Mouse less than a year and it’s already gone [bad] on me, so what’s in store for all those iMac buyers out there? It’s a worrying thought for Apple if other users out there experience the same issues I’ve had with mine.”

MacDailyNews Take: Apple’s Mighty Mouse is a great mouse when it’s clean. It’s the only mouse we’ve found that we actually use the scrolling feature routinely… when it’s clean. We’ve had multiple Mighty Mouse units in action since last August. On average, they have each been cracked open and the Scroll Ball’s tiny magnetic rollers cleaned approximately six (6) times in the past 11.5 months. That’s way too much, Apple. We don’t know how to fix the clogged Scroll Ball issue, but Apple should really work on this problem. Our hands are generally quite clean; we do wash frequently. We can only imagine how quickly a Mighty Mouse in a classroom setting would clog. This whole thing reminds us of one thing: time to go crack open another Mighty Mouse and clean the ball’s tiny magnetic rollers once again. Sigh.

[Update: 1:04pm EDT: We’re back. Cleaning accomplished. Again. Aren’t we fast? We’ve had a lot of practice. A clean Mighty Mouse is a joy! Anyway, for those in need, Apple has an impotent, impractical “How to clean your Mighty Mouse” doc and video on their site, but real instructions on how to clean your Mighty Mouse can be found here.]

  1. I have had a scroll ball for almost a year and have not had to clean it. It still is working fine. (I know I’ll need to clean it sometime). I’m waiting for the dogone wireless MM. C’mon hurry up Apple!

  2. I’ve had two mighty mouses, I just got a new one with my new iMac about four months ago, and then one a few months after the first one came out. I use them lke crazy. No clogs here. Someone needs to wash their hands. Dirty people. YUCK, take a bath.

  3. Have you tired to turn the mouse upside down and clean it like Apple’s website suggest? That does it for me. I’m not too happy about having to do it ever month or so but I’m on my computer about 60 hours a week work/school/projects/play.

  4. Enough of all you whiners and fault-finders. Enough!

    The rest of the computing world has leprosy, but when Apple gets a pimple you scream bloody murder. Dell’s portables catch on fire, but when the Mighty Mouse doesn’t live up to YOUR expectations, it’s the end of the damn world.

    FYI: I’ve had an MM since January, with no problems whatsoever.

    I will continue to come to this site to read the headlines–but little more. You guys can continue to feed on each other and highlight every little boil on the world’s ass.

    You deserve each other.
